Battery OPTIMA or OEM Volkswagen

I've got an optima yellow top & it fit w no problem. No modification whatsoever. You just gotta make sure tha +/- (positive/negative) are reversed.

I purchased a new oem battery today. The 12v 92ah AGM 850A EN/ SAE 520A. Hopefully this solves my current issue. I'll know a little better in the morning on my way to work. At least my key fob works from greater distances now.

I think we have an Optima in our Mk1 diesel.

clean battery post and wires reconnect them and ensure they aRe tight get the voltage tested for free at these automotive stores. 12v when not running, 14v when car is running.

Im running an optima redtop 1000 cca. Starts like a champ in -10 degree weather.

The other day I installed my Optima yellow top that was intended for my S10 into the GTI. Had to cram the battery cover top on a bit, but its on there! Funny now the car starts up alot faster. It always seemed like since I got this car it was slow to start, as if the battery was always low...

I upgraded to an Optima yellow top D35 in my GTI probably about six months go..no problems w/ it at all..the batter cover doesnt fit perfect, but you can make it work...i'm runnin bags with dual compressors and also a jl audio sub/amp system so i needed something with more power..which the yellow top has

Yup, that's the one. The R is for reversed terminals to make it a more ideal fit for our application. Sadly I couldn't find one locally when I needed it so I got the 34/78. It works but isn't a perfect fit as it does require trimming to get the clips on the distribution block to snap back in.

These Optima batteries are crap. Junk. The new battery that i have had for a year now installed in my EOS (that replaced the batteries that were left continually connected to the optimate charger) were tested at Advantage auto parts today and the tester said they only had 180 CCA out of the 750CCA that the battery is rated at. WTF-- JUNK !! I am so frustrated with tis Optima JUNK.

My dad put an Optima red top in his Porsche 930. He used the exact trickle charger you pictured for storage and because the car is driven only a couple of times per month in the summer. The battery was in there 2 years and I had to scramble late Friday night to install a replacement after it wouldn't start at the gas station (friendly attendant helped me bumpstart it). The battery stopped taking a charge.
